LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 525,478, dated September 4, 1894.

Application led November 17, 1893. Serial No. 491,223. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES WIDRIG, a citizen of the United States, residing at Mount Clemens, in the county of Macomb and State of Michigan, have invented a new and useful Lawn-Sprinkler, of which the following is a specification.

My invention relates to improvements in lawn-sprinklers; the objects in view being to 1o provide a sprinkler that is readily set up at any point on a lawn and connected with a hose leading from any source of supply, and which will, through the pressure of the water discharged into the sprinkler cause the latter to vibrate in an erratic manner thus casting the water discharged thereby in various directions, much after the manner of a rainfall; and, furthermore, to provide for a preservation of certain portions of the sprinkler.

zo With these and other objects in view the invention consists in certain features of construction hereinafter specied and particularly pointed out in the claims.

Referring to the drawings:-Figure 1 is a perspective view of asprinkler constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view thereof.

Like numerals of reference indicate like parts in both the figures of the drawings.

3o In practicing my invention, I employ a post or standard l, which may be constructed of wood, a combination of wood and metal, cement, or wholly of metal as desired, and I preferably shape the exterior in such manner as to represent the outlines of a vase in order to render the same attractive and ornamental. The external shape, however, has little to do with the actual practicability of the invention and Whatever shape desired may be em- 4o ployed. There is,however, one requisite and that is that the lower end should be pointed to form a penetrating end 2, and I find it advantageous to enlarge the standard, as at 3, above said penetrating end in that it rests upon the ground and aids in the stability of the standard when the same is inserted in the lawn. The upper end of the standard is in the present instance flared and provided at its center with a longitudinal bore 4, that eX- tends from the upper end to a point in the enlarged portion 3. The bore is for the' most part straight, but gradually deiects toward its lower end so as to emerge from the standard above the penetrating end. The upper end of the bore is surrounded by an annular flange 5, the same extending above the end of the standard and preventing access of water to the bore. The upper end of the bore is also slightly flared and the flange is rounded so as not to offer any sharp edges. A small 6o rubber tube 6, greater in length than the bore, is passed therethrough and projects from the bore at each end. The lower end of the tube is provided with a coupling 7 by which it may be attached in a suitable manner with the garden-hose which leads from any source of supply. The coupling 7 is of course tapered interiorly as is necessary, in that its bore is reduced from that agreeing with the gardenhose to that agreeingwith the rubber-tube. 7o

A metal choke-bandS, of any desired construction is applied at the upper end of-the tube so as to reduce the bore of the same, or, if desired a suitable nozzle may be arranged thereon. This completes the construction, 7 5 and in use the standard is inserted at different points on a lawn and the coupling 7 connected with the lawn-hose.4 It will be understood that when not influenced the small tube atl its upper end hangs limp. The water com- 8o ing from the large hose into the small tube'is greatly increased in force and being suddenly checked or choked in its egress at the upper end of the small tube, serves to straighten the same, causing said tube to move in varions directions as the force of the water is felt, the said tube dropping t0 one side, then suddenly straightening up and swinging to an opposite side, &c., in an erratic manner, causing a thorough sprinkling of the lawn 9o much in the manner of a rainfall.

A device th us constructed is not only very convenient and time-saving, in that it performs the sprinkling in a very thorough manner, but is also an attractive and ornamental feature.

It will be seen that by boring the standard the major portion of the tube is protected against the eifect of the atmosphere, and by flaring the upper end thereof the said tube is roo given a greater liberty for gyrating, and is not liable to be cut out by the upper edge of support and provided with a longitudinal bore emerging at one side of the standard, of a flexible tube arranged within the bore and eX- tending above and below the same and provided at its lower end with a coupling adapting it to be secured to a supply-hose, substantially as specied.

2. In a lawn-sprinkler, the combination with ast-andard having a lower supporting end, and a longitudinal bore, of a flexible tube located loosely for reciprocaton in the stand-v ard and having'an upper discharge'end and its lower end adapted to be connected with a supply-hose, substantially as specified.

'3. 'In a lawn-sprinkler, the combination with a standard having a lower pointed end above which is lformed au external base, a longitudinal boreformed in the tube and aredat its upper end and provided with a. surrounding 3b Iiange, of a iiexible tube located in said bore and provided at its upper end with a chokebaud and at its lower end with a. coupling, substantially as specified. l

In testimony that I claim the foregoing as ggf my own I have hereto affixed my signature in the presence of two witnesses.

yCHARLES WIDRIG.
